Worth knowing
Mailtrap

- The free plan caps sending at 150 emails a day and allows no overage.
- Email Sandbox for testing and Email Marketing for campaigns are priced separately; marketing starts at $15 a month for 10,000 contacts.
- Overages are capped, so senders far above their plan's volume are told to upgrade.
Resend
- Billing is monthly only; there are no annual plans or yearly discounts.
- There is no plan between Free and the $20 Pro plan, and the free plan caps sending at 100 emails a day.

- Marketing email is priced separately by contacts, from $40 a month for 5,000; broadcasts do not use the transactional quota.
